Shocking treatment from planet fitness

I joined planet fitness in January 2018 at the Cape Town city gym on a 12 month contract.in February 2018 I froze my contract due to a injury and because I still hadn't recovered by the end of May I asked planet fitness if I could cancel my contract.They said that if I was to cancel my contact they wanted a settlement fee of r1976 which I paid on the 31st may.on the first of June they took another debit order of r125 and then on the 15th june they took another debit order of r540 even though I had paid them r1976 as a settlement figure....so please do not ever sign a contract with this company because they will take money from your bank account even though they are not entitled to it.
